Extremely bad performance of the Modrinth App (Linux)

[JustCyra]

Please confirm the following.

• I checked the existing issues for duplicate problems
• I have tried resolving the issue using the support portal
• I have ensured my Modrinth App installation is up to date

What version of the Modrinth App are you using?

0.9.2

What operating systems are you seeing the problem on?

Linux

Describe the bug

Using Pop!_OS 22.04 LTS with the .deb and Appimage packages

Trying to do anything makes the app run at ~1fps, making it extremely unwieldy. Only thing is "unaffected as much" is the category selections on the Settings page of the app.
Turning Advanced Rendering on and off doesn't seems do anything regarding the issue.

Steps to reproduce

1. Open the app
2. Do literally anything

Expected behavior

No performance issues, again

Additional context

I've made a report on this exact same issue before the UI redesign: #1222
However this time it appears to effect almost every aspect of the app

My laptop does have integrated and dedicated graphics, but even if the app was using integrated, it wouldn't be THIS bad of a performance

OS: Linux x86 64-bit (Pop!_OS 22.04 LTS)
GPU: Nvidia GeForce GTX 1660 Ti Mobile
GPU Driver: Nvida Driver 560.35.03

App:
Modrinth App 0.9.2
Linux 22.4.0

Also something to add that when doing literally anything one of my CPU cores max out to 100%, alternating between different cores but always consistently only 1 being maxed to 100%. Doing nothing on the app doesn't seem to do anything weird with the CPU cores

Having an extremely similar experience on debian 12 (with 3070 rtx and 535 nvidia drivers iirc), also with both the appimage and deb package. Just about any icon, if hovered over, creates extreme lag/low fps and usually maxes out one of my cpu cores to 100%. Also exception (at least on the main home page of app) seems to be the news section/icons. Those dont seem to lower fps or create any big cpu stress.

#1216 is the issue if you were looking for that :)

Same issue as #3057, the app has become unusable on Linux+Nvidia. But for your case, running it on integrated graphics and enabling hardware rendering should work. Something like DRI_PRIME=1 /opt/modrinth-app/modrinth-app I think

Same here. Arch linux rolling, X11, i3, proprietary nvidia drivers. In case this helps anyone, reducing window size alleviates the issue (less pixels).

This didn't work for me. I have the same issue on Linux Mint 21.1 with the nvidia driver 535.183.01, with both the .deb and the .AppImage.

Do you have integrated graphics? The important part is not running the app on Nvidia graphics, because of a crash issue with Nvidia's drivers, and enabling hardware rendering, because the slowness is caused by software rendering (which was enabled by default to work around the Nvidia crashes).

If you can, try flatpak version.
